Bill, I take it that these were all in-camera multiple exposures, yes?
Hi Ken, yes, they were 15-20 exposures for the purpose of focus
stacking. I wanted to use the lens at it's best aperture and have
excellent sharpness front to back, and also I only have 6 stop and 10
stop ND filters, so everything was a bit of this and a bit of that. Even
at f/16 I wasn't getting enough depth of field, so I was destined to
focus stack no matter what. I wanted the water very blurred, hence the
longish exposures. If I had been using large format, I would have been
ISO 12 f/64 for 5 1/2 minutes, so this is still a long way off the
exposures I would have been using in my 4x5 days. I could have used the
10 stop filter, but this seemed to work in this location. With focus
stacking I was able to secure the depth of field that I desired that I
could have gotten easily with the movements on the view camera and that
I have found difficult to acquire with box cameras.
thanks

Of the 4 you've shown us so far, 20186 is my favorite... it's nice to
accomplish capturing the smooth milky water as a blur, it isn't what one
can see
when you are actually in that place.. The texture of the water in the
this one takes me there.. it looks like what my eyes can see - nice
geometry too.

My goal with these pictures was to try, to a certain extent, to
emulate what I used to be able to do so easily with 4x5 film, which
was get really deep depth of field along with tremendous detail, while
at the same time introducing sufficient blur into the moving water to
turn it to milk.
To get this result, I needed to shoot at the best aperture and then
stack the images, and use multi stop neutral density filters to expand
the exposures out. I decided to throw the polarizer on mostly to see
what it would do.
This was the sort of thing I would have done with Ilford Pan-F rated
at ISO 12 or so, and using an f/stop of 45 or even 64.
Overall I am pleased with the result.
Oh and, comments welcome.
Thanks
